libgimp: new function gimp_procedure_dialog_set_sensitive_if_in().
This function allows to change the sensitivity of a widget depending on the value of another property. We already had gimp_procedure_dialog_set_sensitive() except it was only syncing with a boolean property, whereas the new function can compare with any property type.
